TAT PATENT SHINGLE-BRACKET.

To all whom it may concern:

Be it known that I, VERSAL D. Kine, a citizen of the United States,residing at Greensboro, in the county of Orleans and State of Vermont,have invented certain new and useful Improvements in Shingle- Brackets,of which the following is a specification, reference being had thereinto the accompanying drawing.

This invention relates to scaffolds of the type which are principallyused in shingling a roof and the principal object of the same is toprovide a means whereby the scaffold nay be adjusted so that thescaffold may be used on roofs slanting to different degrees and yet havethe platform of the scaffold horizontal.

This invention is illustrated in the accompanying drawings, whereinFigure 1 is a perspective view of the improved scaffold and shows thesame positioned upon a roof. Fig. 2 is a side view of the scaffold. Fig.3 is a bottom plan view of the scaffold. Fig. l is an enlarged view ofone of the struts. Fig. 5 is a view of one of the struts looking fromthe opposite side from that shown in Fig. 4;. Fig. 6 is an enlargedsectional view of a portion of one of the struts and shows the manner ofconnecting the two sections. Fig. 7 is an enlarged fragmentary view ofthe end of one of the struts.

Referring to the accompanying drawings by numerals it will be seen thatthe improved scafiold comprises a platform 1, which is preferably madefrom wood. A pair of supporting bars 2 and 3 are secured to the undersurfaces of the platform 1 by means of the bolts A which pass throughthe platform and bars. The supporting bars are secured at one end nearthe center of the platform and are outwardly curved and have their endspositioned near the sides of the platform. The ends of the braces arerolled to provide housings 5 and 6, the housings at each end of thebraces being in alinement. The rods 6 and 7 are passed through thealined housings, and have their outer ends extending beyond the outerends of the housings.

A strut is positioned upon each outer end portion of the rod 7 and holdsthe platform in a horizontal position. The strut comprises an uppersection 8 and a lower section 9. The section 8 has its upper portionrolled to form a housing 8 which surrounds the outer end Specificationof Letters Patent.

portion of the rod 7, and by means of which the strut is pivotallyconnected with the rod. The struts are held upon the rods by means ofnuts, or any other desired means. The lower section 9 is provided with apair of arms 10 which surround the section 8 and form a means forslidably connecting the sections together. The section 8 is providedwith an opening near its lower end and the section 9 is provided with alongitudinal series of openings 11. A bolt 12 passes through one of theopenings 11 and through the opening formed in the end of the section 8to hold the strut in an adjusted position, the bolt being held in placeby a wing nut 13. The lower ends of the section 9 are rolled to formhousings I L through which there is passed the rod 15, which extends toeither side of the housings. The fact that the ends of the braces havingthe housings 5 curve toward the sides of the platform brings thehousings 5 and 14: in alinement and, as the rods 6 and 15 are ofapproximately the same length, there is an equal amount of rod extendingto the sides of the two sets of housings.

A pair of ties 16, each has its ends filed to provide a pair of upperclaw teeth 17 and lower claw teeth 18. The upper teeth are bent backupon the body of the tie at approximately an angle of 45 degrees and thelower teeth are curved downwardly and approximately at an angle parallelwith the angle of the upper teeth. A strip of metal 19 is secured to theupper portion of each of the ties and has its free end curved to form ahousing 20, which surrounds the outer ends of the rod 6 and which isheld in place by means of nuts, or other desired securing means. Asimilar strip 21 is secured near the lower end of each of the ties andhas its free end rolled to provide housings 21 which are mounted uponthe outer ends of the rods 15 where they are held by means of nuts orother desired securing means.

In the operation the angle of the roof is ascertained and the struts aremoved to bring the ties at approximately the same angle to the platform.The platform is then placed upon the roof and the claw teeth 17 and 18sink into the roof as clearly shown in Fig. 2. By means of having theupper teeth and the lower teeth positioned at an angle shown there is nodanger of the platform slipping as the greater strain there is placedupon the platform, the deeper the teeth will sink into the roof, and thetighter the platform will hold. It should be noted however, that theteeth do not sink deep enough into the roof to cause the same to leak.

lVhat I claim is A device of the character described, comprising anadjustable platform, curved supporting bars secured to the under side ofsaid platform, the inner Widely spaced ends of said supporting barsbeing secured upon a transverse rod at the inner side of said platformand the other more narrowly spaced ends being secured upon a transverserod which is carried by the upper sections of adjustable struts whichsupport the outer portion of the platform, and means to connect thelower ends of said adjustable struts with an inner transverse rodsecured upon toothed ties which are also secured upon the firstmentioned transverse rod.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
